Magnetic drum

Magnetic drum

Drum memory was an early form of computer memory that was widely used in the 1950s and into the 1960s. For many machines, a drum formed the main working memory of the machine, with data and programs being loaded on to or off of the drum using media such as paper tape or punch cards. Drums were later replaced by core memory, which was faster and had no moving parts, and which lasted .

History of Memory and Storage Systems

Magnetic Drum Memory (1947) While rotating the drum, an electromagnetic pulse which represented a bit value could be stored by changing the magnetic orientation of the ferromagnetic particle that the write head passed over at that very moment. Many machines used magnetic drum memory in the 1950's as what we call today main memory, to execute programs. David Macklin shared a story with .
